8.0. 3.3V Voltage Regulator
The
LV24-33 v6
development system is provided with a voltage regulator whose purpose of which is to reduce the power supply
voltage of the development system from 5V to 3.3V. The 3.3V power supply voltage is then used for powering the microcontroller
and other on-board modules. The MC33269DT-3.3 circuit provided on the development system is used as a voltage regulator
capable of providing 800mA current.

9.0. USB Communication Module
The CN23 USB connector enables a dsPIC with a built-in USB interface to be connected to peripheral devices. The microcontroller
is connected to the CN23 connector via USB-DM and USB-DP lines. The function of the LED marked as ON is to indicate connection
between USB devices and development system, hence the microcontroller.
